Hydrologic Outlook

1155 AM PDT Tue Mar 19 2019

...Warmer Temperatures Will Increase Snow Melt This Week...

Snow melt will continue to accelerate across the region over the
next several days as warmer temperatures are seen. High temperatures
by the end of the week are expected to be in the mid 50s to lower
60s with overnight lows in the 30s to lower 40s.

In addition, a weather system will be moving through the Pacific
Northwest Friday through Sunday, with mainly light rain. Snow
levels are expected to start out between 6000 to 7000 feet and
lower to 4500 to 5500 feet on Saturday.

Ditches and small streams are filling with snowmelt and slush.
There may be some local areas with frozen soils near the surface.
This will keep melt water from soaking in and may result in local
areas of lowland flooding, water over roads and field flooding
flooding.

Water flowing into creeks and streams will increase as well, both
in the lower elevations and in the mountains with streams and
creeks becoming full. The flowing water may increase the
potential for ice jams on any still frozen rivers. At this time,
no flooding is expected on the larger rivers.

Impacts will depend on how fast the snow melts. Continue to
monitor the forecast for the latest details.
